Entretien
Plant in well-draining soil and provide consistent moisture, especially when young. Cut back old foliage in late winter or early spring before new growth emerges. It tolerates a range of conditions once established.
- Watering
- Water regularly during the growing season, allowing the soil to dry slightly between waterings. Reduce watering in fall and winter.
- Feeding
- Generally does not require regular fertilization; a light feeding in spring is sufficient if needed.
- Pruning
- Cut back all dried foliage to about 2-4 inches above the ground in late winter or early spring, before new growth begins.
